Spring 注解@Transactional
在使用@Transactional注解前需于下配置,两种方式都可以。
xml
<bean class="org.springframework.transaction.aspectj.AnnotationTransactionAspect"
        factory-method="aspectOf">
        <property name="transactionManager" ref="transactionManager" />
</bean>
JAVA
 1 @Repository
 2 public class TxService {
 3     private DataSourceTransactionManager txManager;
 4     
 5     @Resource(name="dataSource")
 6     public void setDataSource(DataSource dataSource) {
 7         txManager=new DataSourceTransactionManager(dataSource);
 8         // configure the AnnotationTransactionAspect to use it; this must be done before executing any transactional methods
 9         AnnotationTransactionAspect.aspectOf().setTransactionManager(txManager); 
10     }
11     
12     public DataSourceTransactionManager getTxManager() {
13         return txManager;
14     }
15 
16 }

@Transactional使用实例
  // these settings have precedence for this method
@Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW)
public void updateFoo(Foo foo) {
// do something
}

 @Transactional 可配置属性
